| General description【一般描述】 | Superoxide dismutases are a group of low molecular weight metalloproteins present in all aerobic cells of plants, animals and micro-organisms. They provide protection against damaging reactions with the superoxide radical anion (O2-) by catalyzing its disproportionation into oxygen and hydrogen peroxide. |
| Application【应用】 | Superoxide Dismutase from bovine erythrocytes has been used in a study to assess activity parameters in adjuvant-induced arthritis. Superoxide Dismutase from bovine erythrocytes has also been used in a study to simplify the process of purifying superoxide dismutases using charge-controlled hydrophobic chromatography on 10-carboxydecyl Sepharose. |
| Biochem/physiol Actions【生化/生理作用】 | 催化超氧化物自由基的歧化反应生成过氧化氢和分子氧。在细胞防御氧自由基的毒性作用方面发挥着重要作用。与一氧化氮(NO)竞争超氧化物阴离子(可与NO反应生成过亚硝酸盐)，因此SOD能促进NO的活性。在培养的大鼠卵泡、神经细胞系和转基因小鼠中，SOD也表现出抑制细胞凋亡的作用。 |
| Unit Definition【单位定义】 | One unit will inhibit reduction of cytochrome c by 50% in a coupled system with xanthine oxidase at pH 7.8 at 25 ℃ in a 3.0 mL reaction volume. Xanthine oxidase concentration should produce an initial ΔA550 of 0.025 ± 0.005 per min. |
